A plucky 91-year-old stroke survivor jumped on a conman's back and ordered him out of her home after he tried to force his way inside. <br /><br />Eva Gentzsch-Clark, who is just 5ft 1ins tall, sprung into action when the fraudster pushed her to the floor as he tried to gain access. <br /><br />The man claimed to be from the water board and asked to read her meter, but she grew suspicious when he handed over a fake letter as ID. <br /><br />He barged past her and began raiding her home but Eva jumped on top of him and forced him to flee empty-handed.
